ADN-444 Sumire Kurokawa, The Sober And Taciturn Sister Next Door

An unsociable neighbor who doesn't greet you when you pass each other. She seems to have a boyfriend, and at night she always hears pant voices. She was beautiful and had a good style, but somehow she always seemed to lack confidence. Why…? When I was thinking about such a thing, I heard an angry voice from next door. When I went outside, I saw my neighbor sitting on the ground.
